Application March 31, 1934, Serial No. 718,498

4 Claims.

This invention relates to an improvement in the construction of watches and more particularly in an improved method of securing and orienting the dial of a watch, the dial also functioning to hold the watch movement in proper position.

In the form of construction heretofore employed, the watch dial has been afiixed to the watch by means of two or more pins which project from the rear of the dial and into apertures in the watch movement. The dial has been secured in place by the engagement of a shoulder on the bezel of the watch with the periphery of the dial. Because of the wide variety of designs and arrangement of watch movements or works the positioning of these locating pins in the dial varies greatly. This practice has resulted in a greater cost in the manufacture of dials in that it necessitates making and stocking dials, the pins of which are located in various positions to accommodate the location of the holes for same in different watch movements. This practice has prevented the standardization of watch dials.

It is the object of this invention to provide a construction for the retention of a watch dial which will overcome the aforesaid objections and which will permit the manufacture of dials in standard dimensions to fit onto a watch having works of any manufacture and to provide a simple and economical method for attaching the watch dial.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the" drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In describing the invention in detail and the particular physical embodiment illustrating the invention, reference is had to the accompanying drawing wherein like characters of reference designate corresponding parts thruout the several views.

In the drawing:

Fig. 1 is an elevational view of the face of a watch.

Fig. 2 is a sectional view of an entire watch taken on the staggered line 22 of Fig. 3.

Fig. 3 is an elevational view of the watch case; and

Fig. 4 is an elevational view of the rear of a watch dial.

Referring to the drawing for a more detailed description thereof, numeral 5 indicates a watch case having a circular opening 6 in its center adapted to receive the movement or works of the watch. The periphery of the opening 6 provides an annular shoulder '7 adapted to engage With a recess in the Watch works. The watch case is further provided with apertures 8 in juxtaposition with studs 9 attached to and projecting from the rear of the watch dial 10. In the preferred form of construction illustrated I have shown these studs 9 having an interiorly threaded portion 11 which is adapted to receive screws 12, which, when installed, will retain the dial securely to the watch case. This form of construction further provides a means for retaining the watch movement in the case by the engagement of same between the dial l0 and the shoulder 7 on the watch case 5, the movement being otherwise unsecured to the case. The positioning of the apertures 8, as shown in Fig. 3, spaced from either center line of the watch case 5 prevents any error in the orientation of the watch dial 10 thereto.

The drawing further illustrates in the usual construction a bezel 14 retaining on its face a crystal 15, the bezel being adapted to snap onto the periphery of the watch case 5. The case back 16 is also retained on the watch case 5 in similar manner.

What is claimed as new is:

1. The combination, with a watch case having apertures extending from the front to the back thereof, of a dial plate provided with interiorly threaded hollow studs extending from the back thereof and lying in said apertures of the case, and screws engaging the threads of the studs and having heads abutting the back of the case.

2. The combination, with a watch case having apertures, of a dial plate provided with studs extending from the back thereof and lying in said apertures of the case, and means for fastening said studs to said case.

3. The combination, with a watch case having a recess, a movement in said recess, said case having apertures, of a dial plate provided with studs extending into said apertures, means for fastening said studs to said case, said movement contacting the back of the case and the dial whereby the dial assists in holding the movement in position.

4. The combination, with a watch case, of a watch movement therein, a dial secured to the front face of the case and retaining means for the movement at the back of the case, said dial pressing said movement against said retaining means to hold the movement in position.
